Toronto police were scouring the 7th floor of a downtown apartment building for evidence Friday after a 2-year-old girl was found dead.

Paramedics said they were called to the Toronto Community Housing building at 200 Wellesley St. E. shortly after 9 a.m. They treated the toddler, but it was too late, said EMS spokesperson Kim McKinnon.

“She was pronounced dead at the scene,” McKinnon said.

Police said the child was in the care of a teenager at the time.

Police are characterizing the toddler’s death as suspicious, although it is unclear if foul play was involved. Homicide investigators routinely investigate sudden deaths of children younger than 5.

An autopsy is expected to reveal details about the girl’s death by Monday.
